Rubber bumpers 11 project use have several outstanding defects, among laterally from the door jamb so as to be enthe more prominent of which are the ingaged by the door 5 to prevent rattling of ability of the horizontally-sliding latch-bolt the door against the jamb. The latch-bolt 1 to automatically compensate for the varying 8 is adapted tobe thrown from the outside 70 distances between door and jamb as the usual of the door by a handle 12 and from the inrubber jamb bumpers become worn or disside of the door by a handle 13, as hereinplaced and the unsightly open slot in the after described. I

The the door and an'edge flange 15 apertured to present invention has for its primary object permit the swinging of the latch-bolt 8 therethe elimination of these defects, and accomthrough to any desired degree. The latchplishes this by mounting both the latch-bolt bolt 8 is pivoted on the pin 16 journaled in and the handle of the inside opening lever flan es 17 of a bracket or yoke 29 carried 80 to rotate in horizontal planes with pin and by t e plate 14:. A spring 18, herein shown slot connections between to permit the latchas fulcrumed on. the in 16, tends to press bolt to swing through greater or lesser arcs the latch-bolt outwar ly to its fullest extent. as needed to compensate for the wear. of the A connecting link 19 is pivoted at one end rubber bumpers. to the latch-bolt 8 through apin 20 fitted A further object is the provision of a into ali ed apertures in the sides of the simplified construction including the arlatch-b0 t, and adjacent its other end is prorangement of lips or flanges on the lock casvided with an elongated slot 21 for the reing to guide the latch-bolt and connecting ception of the pin 22 fitted into aligned aper- 35 links in. their movements while preventing tures in the upturned flanges 23 on the forthe accidental dislocation of the verticall ward extremit of the traveler-link 24. The disposed pins connecting the links to eac slot 21 and pin 22 are. arran ed to permit other and to the latch-bolt. movement of the lock-bolt 8 mdependentl The above and other objects of my invenof the traveler-link 24, whereby the lock-b0 t 40 tion will be apparent from the following deis permitted to automatically take up any scription wherein reference is made to the wear of the rubber bumpers 11 by swinging accompanying drawings illustrating a preoutwardly through slightly greater arcs. ferred embodiment of my invention, and The pins 20 and 22, when in operative posiwherein similar reference numerals desig tion, are vertical and some rovision must be 5 nate similar parts throughout the several made to prevent their fall by gravity. This views: is accomplished in the construction herein In the drawings: shown by extending the lower flange 17- of Fi 1 is a perspective view of an autothe bracket29 for a sufiicient distance to en-' mobi e door and adjacent casing with the age the lower extremity of the pin 20 door in open position; Y note dotted line in Fig. 4-) and by bend Fig. 2 is an end view of the lock removed ing a lip or flange 25 from the cover plate from the door; 43 to sup ort the lower extremity of the pin Fig. 3 is a front elevation of the lock; 22 (note i 5) I Fig. 4 is a cross section taken substantially The trave er-llnk 24- is provided with an F on the line 4-4 of Fig. 3; upturned flange 26 adapted to be engaged cover plate 43 (see Fig. 6) and is held against vertical movement by means of a ring 30 secured on the lower extremity of the spindle and projecting througha slot 31 in the plate 14. It will be evident that this arrangement of the s indle 28 requires only an aperture in the window sill of sufiicient area to permit clearance of the spindle, and thereby renders unnecessary the elongated slot in the window sill now generally used to permit a vertically-swinging lever to operate. The handle 13 may e suitably. secured to the upper extremity of the spindle 28, as by the screw 32. They outside handle 12 is rovided with a squared shank 33 fitting wit hin an aperture in the hub 34' of the lever 35, which lever is arran ed be-v tween the edge fiange 15 of the p ate 14 and a projection 36 on the traveler-link 24 (see Fig. 3) whereby, it normally provides a stop memben, forlimiting the forward movement of thetraveler-link. When the outside handle is turned the lever 35 is swun to force the traveler-link rearwardly and t rough theconnecting-link 19 swings the latch-bolt 8. When t e handle is released, the spring 37 engaging therear ex tremity of the traveler-link returns the members to their normal position, as shown in Fig. 3. r

When it is desired to lock the doors of the automobile to prevent their being opened b rotation of the outside. handle 12 the late 38 is swung downwardly into the dotted line position shown in Fig. 3 engaging the lever 35 to prevent its travel. All but one ofthe doors of the automobile are locked with their latches 38 engaging the levers 35, and the remaining door is ocked from the outside of the car through a ke -controlled lock. Any preferred type 0 key- 8 controlled lock can be used in connection with this v invention, the lock-controlled shank 39 being arran edto engage the vertically-moving slide p ate 41 having a flange 42 normally resting out of the path of movement of the traveler-link 24, but guided for movement into the path of the traveler-link 24 whenever the plate 41 is-moved. A cover plate 43 is secured over the working porto be aglparent.

tions of my improved door lock and a slot 44 therein is preferably arranged to guide the flange 42 in its movements.

The operation of my door. lock is believed The spring 18. normall presses t elatch-bolt 8 outwardly and 1101 s it in engagement with the securing plate 9 to prevent the accidental opening of the door. When it is desired to open the door rotated, swinging the lever 35 tom'ove the traveler-link 24 rearwardl and throu h the connecting link 19 swinging the late -bolt 8 inwardly to release the door.

The operating parts are returned to their normal spring3 and the door can be again locked by merely pulling the door into engagement with the ]amb,.the latch-bolt 8 swinging against the tension of the spring 18 to permit the inward movement of the door and then catching within the striker plate 9 to secure the door in closed osition.
